The CAST Test: A Complete Guide

Nov 12, 2024

Working within the construction, utilities, and skilled trades industries can be challenging and demanding. Individuals are required to have specialist knowledge in a range of areas both to perform tasks associated with their jobs, and to ensure their safety and that of others while working. 

The CAST (Construction and Skilled Trades) Test – sometimes called the EEI CAST Test – is commonly used by employers and recruiters to evaluate skills and knowledge required for working in these industries. 

Within the guide, you’ll find everything you need to know about preparing for the CAST Test, as well as helpful tips for performing at your best on assessment day. You will also find CAST practice questions to aid you in your CAST Test preparation. 

 



 

What Is the CAST Test?


Created by the Edison Electrical Institute (EEI), the CAST Test is a 110-question, multiple choice exam used by employers within the construction industry and utilities sectors as part of their recruitment processes. Testing is organized by employers with potential candidates and will usually involve arranging a meeting to complete the assessment as it’s paper-based. 

The CAST Examination aims to assess knowledge and skills required for a wide range of construction and skills trades jobs including electrical repair, vehicle repair and meter services and repairs. Assessing abilities like math, mechanical concepts, and critical thinking, employers use information provided by the CAST Test to identify candidates with the skills required for specific roles. 

There isn’t a specific passing score for the CAST Test, as tests are administered by individual employers for a range of different roles. The score required will be set by employers as their benchmark for potential new employees.

Successful completion of the EEI CAST Test is often essential for moving to the next stage of the recruitment process or being offered employment by your preferred company.

Note that this is different to the CAST Test (California Science Test, sometimes called the CAST Science Test), which is given to students who attend school in California.

 



 

Key Sections of the CAST Test


The CAST Test is composed of four separate, timed test papers: graphic arithmetic, mathematical usage, mechanical concepts, and reading for comprehension. Each paper is designed to evaluate a different set of skills and areas of knowledge.

Each of the papers has a separate time limit, so it’s important to answer questions both quickly and accurately to achieve the highest score you can.
